                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Barentine
 Opened at 18:50 under clearing skies and moderate winds.  Clouds were
intermittent during most of the first half but did not unduly interrupt
observations.  Don noted the slitviewer problem (freezing up) documented
in Russet's PR of tonight.  We also experienced some net slowdown around
22:15.  Cloud situation got worse after 22:30, being nearly overcast at
times.
 2nd Half Observing Specialist: N.C. Hastings
   Clouds were thick at the time of switchover and rain threatened. We
remained closed until the threat passed. It remained very cloudy with some
rain until almost 5am, then suddenly cleared up. We did get an hour of
science at the very end.
